FaceID/Face Unlock failing in low light
4.5
The phone cannot recognize your face when you are in a dark room.
Symptoms
- "Face not recognized"
- PIN prompt
- Infrared dots visible but fail
Possible Causes
- Poor IR sensor performance
- Obstructions
- Software bug
Step-by-Step Fix
1
Increase Screen Brightness
The screen light can help the camera see your face better.
2
Re-scan in Low Light
Some phones allow you to add an "Alternate Appearance" in dark conditions.
3
Clean Sensors
Wipe the "notch" area to ensure the IR projector is clear.
When to See a Technician
True FaceID uses infrared, so it should work in total darkness. If it doesn't, the IR projector might be failing.
